When creating polymer-based composites, plain weave fabrics and micron-sized fillers offer bidirectional strength and reduced voids/inhomogeneity. In the present work, It was investigated how glass fabric reinforced epoxy composite (G-E) performed during three-body abrasive wear with and without ceramic fillers (SiO2, Al2O3, graphite, and fly ash cenospheres). In experiments, loads of 20 N and 40 N were applied at various abrading distances of 500 m, 1000 m, 1500 m, and 2000 m. According to the results of sand abrasive wear test, the specific wear rates of G-E based composites are sensitive to fibre and filler/matrix adhesion. Under all tribo-test settings, the SWR for all particulate G-E composites decreases in the following order: G-E > Gr/G-E > SiO2/G-E > Al2O3/G-E > fly ash cenosphere/G-E. Furthermore, the specific wear rate of the fly ash cenosphere filled G-E composites were found to be lower than the G-E and other filler materials filled G-E composites. There was 38.7% reduction in the specific wear rate at 40 N, 2000 m in fly ash cenosphere filled G-E composite. As per the evidence of scanning electron microscope images of worn-out surfaces, mechanisms such as ploughing, fibre breakage, fibre pull-out, fibre thinning, and a network of microcracks caused the wear in composites.

In more than 90% of hip replacements, the acetabular cup is made of ultra-high molecular weight polyethylene (UHMWPE) and the femoral head is made of stainless steel, cobalt-chromium-molybdenum alloys, titanium or ceramic. The primary factor in evaluating soft-on-hard endoprostheses is the maximum contact pressure as the contact strength of UHMWPE. The level of these pressures is used as a criterion for the correct selection of the femoral head size and radial clearance in the connection during arthroplasty for a specific patient. According to the previously developed new analytical method is proposed for estimating maximum contact pressures in thermo-diffusion nitrided (TDN) titanium GRADE 2 – UHMWPE hip joint implant. The effects of implant femoral head diameter and radial clearance on maximum contact pressures are determined for the average load. Relationships between maximum contact pressures and the above-mentioned parameters are established. A comparison is made between maximum contact pressures estimated by the proposed analytical method and numerical analysis with ANSYS (2D and 3D). The maximum contact pressures calculated using the 2D model have been found to be the lower limit, and the pressures calculated using the 3D model in ANSYS are the upper limit for analytical calculations. Therefore, it should be expected that at thickness of cup ˜ 7…8 mm the contact stresses will not be significantly different than those obtained from the solution by the above method. The developed analytical method can be effectively used for research not only soft-on-hard endoprostheses (metal-on-polymer, ceramics-on-polymer), but also hard-on-hard endoprostheses (metal-on-metal, ceramics-on-ceramics). The results of analytical calculations were also related to the results of FEM calculations known in the literature and their convergence was established.

Intermittent turning (IT) is characterized by a different context than continuous turning (CT). The cutting tool is shocked each time it goes off-load and engages a new surface. This interruption causes severe cutting conditions, which fatally affect the performance parameters. The purpose of this study is to assess the effects of four cutting factors, tool nose radius (r), cutting speed (Vc), feed rate (f), and depth of cut (ap), on the following output performance parameters: surface roughness (Ra), cutting temperature (T°), and cutting tool wear (VB) during turning (IT) AISI D3 cold work tool steel. A triple CVD (AI2O3/TiC/TiCN)-coated carbide cutting tool was used. A Taguchi L9 (3^4) experimental design was adopted for carrying out the experiments in intermittent turning. To improve the performance parameters based on three (3) highly particular scenarios that fulfill industrial criteria, the desirability function (DF) and the grey relational analysis method (GRA) were used. Finally, the optimization findings of the two strategies were compared in order to evaluate the performance of each method.
